http://bugs.winehq.org/show_bug.cgi?id=21394

Summary: nul: nul and + doesn't not work for copy.
           Product: Wine
           Version: 1.1.35
          Platform: x86
               URL: http://www.ghostscript.com/
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: cmd
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

am running nmake with win 7 sdk (vc 9 express) to build ghostscript . most of
the build procedure ork as is, but a script used for copying files from one
directory to another (gs/base/cp.bat)

-----------------------
@rem $Id$
@echo off
if "%2"=="." goto ne
if exist _.tmp erase _.tmp
rem     Both of the following lines are necessary:
rem     the first one works on MS DOS and Windows 95/98 but not Windows NT,
rem     the second works on Windows NT but not the other MS OSs.
rem > _.tmp
copy nul: _.tmp > nul:
copy /B %1+_.tmp %2
erase _.tmp
goto x
:ne
copy /B %1 %2
:x
------------------------

does not work - using it as it result in a few "Path not found" about the use
of nul: and also joining files ("+"). Granted nmake -f psi/msvc32.make works on
windows.
